SiegeStones is the second game published by Live Oak Games. In this one, players are trying to capture four towers. The wooden board starts empty, and has a very simple design of 37 circles on it. Players take turn placing either a "stone" or a "tower" on the board. Stones threaten towers - whichever color presents the greatest threat to a tower controls it. Towers weaken stones. The board is scored after each player's turn. Once placed on the board, a tower changes ownership back and forth as players try to gain control of it. The beginning of the game is very open, the midgame very strategic and challenging, the endgame is often a "grab" for the final tower.
